ARTHUR E. FEAGAN AND JAMES C. NELSON, OF MARINE CITY, MICHIGAN.

TROLLEY-POLE.

Application filed June 7, 1915.

To, all whom it may concern Be it known that we, ARTHUR E. FEAGAN and JAMES C. NELSON, citizens of the United States, residing at Marine City, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Trolley-Poles, of which the following is a specification, reference being had to the accompanying drawings.

Our present invention relates to new and useful improvements in supporting sockets for trolley poles and as its primary object aims to provide a socket which consists in two detachably connected sections, one of which is designed for attachment to the trolley stand and the other of which is adapted to support the trolley pole.

A more specific object of the invention is to provide a socket in which the two sections are provided with coupling disks which are adapted to be clamped together by means of a clamping bolt and to associate with the disks, shoulders which are adapted to engage with each other when the two sections of the socket are in longitudinal alinement with each other, thereby making it possible for the workman installing the pulley to accurately determine, without the aid of a light at night-time, when a new wheel carrying section of the poleis properly set.

A further object of the inventionis to so construct the coupling disks that the upper section of pole carrying portion of the socket may be loweredto dispose the trolley wheel in reach of a workman standing on the car route and may then be secured in such adjusted position.

The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form part of this appli cation.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention, as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a side elevation showing the pole applied to a trolley stand; Fig. 2 is a detail edge view looking at the coupling disks of the two sections of the trolley pole; Fig. 3 is a face Specification of Letters Patent.

view of the joint between the two sections of the pole; Fig. 4: is a section on the line 1-4, of Fig. 1.

As embodied in the accompanying drawlngs the trolley pole of our invention includes in its preferred form, two sections 10 and 11, the former of which is designed for attachment to the trolley stand, indicated conventionally at A and the latter of which is designed to support the trolley pole, indicated at B. The two members 10 and 11 are formed as relatively heavy metal castlng. As a means for detachably connecting the members 10 and 11, I provide each of them with a coupling disk, as indicated at 12 and 13. These members 12 and 13 are provided upon their inner faces with ratchet teeth indicated at 141 and have a combined thickness approximately equal to the diameter of the stem portions 10 and 11. A segmental stop shoulder or flange, indicated at 15 extends from the terminal of each of the members 10 and 11 and around the edge of the disk carried thereby, as shown in Fig. 1. These stop flanges are of a width approximately equal to the combined thickness of the two disks so that when these two members are mated, as shown in Fig. 2 the terminals of the stop shoulders will engage in a line which extends completely across the joint. In the disk 12 is formed a centrally located opening 16 which is adapted to receive an axle 17, which projects laterally from the inner face of the disk 13 and is centrally disposed with respect thereto.

The axle is terminally threaded, as dis closed best in Fig. 4 to receivea locking handle, indicated at 18. This handle is formed from a short bar of metal and is provided with an internally threaded terminal socket which is adapted to be threaded upon the axle to serve as a clamping nut for holding the ratchet teeth of the two disks in engagement with each other. It has been found preferable in practice to bore out the inner faces of the two disks at the approximate centers thereof to form the annular recesses 19 wherein may be seated a washer 20.

The stem portion 10 of the section 10 is seated in the socket 21 which is of. the usual type provided in connection with a trolley stand and is held against withdrawal therefrom by bolts or equivalent fastening devices indicated at 22. The stem portion 11 of the section 11 is formed in the nature of a sleeve or tube which serves as a socket wherein the lower end of the trolley pole indicated'atl23is seated The trolley pole is held against withdrawal from the socket 11 by bolts or equivalent fastening devices which, as illustrated at 24:, pass through the member-"11 and'through the trolley'pole as is best shown in detail in Fig. 1.

7 From the foregoing description taken in connection with the accompanying draw-V ings, it will now be readily apparentthat the disk sections of the trolley pole may be quickly connected by placing the two clamping disks in mating relation with their ratchet teeth in engagement with each other. Obviously, the lockinghandle may be rotated upon the axle to draw the two disks" 'into'clamping engagement with each'other sothat the teeth of the two disks may not become separated. Referring now to- Fig.

' 2, it will be seen that when the terminals of quiring alamp or light at any ti1ne,"when the section 11 is properly positioned with respect to the section 10 for by the use of his fingers,: he can readily tell when the two flanges are in engagement with each: other. We now desire to directparticula-rattention to the-factthat by providing-two fiatdisks as the coupling by which the two sections ofv the trolley pole may beconnected, we insure the propermountingof the trolley wheel at all times, forthe two disks when flatlyengaged against each other, will insure the positioning; of the trolley wheel with its axes of rotation in transverse relationto; the trolley wheel B.

.It will now be noted thatin-case it is desired to place a new trolley wheel in the" upperisectionof the pole, the handlemay be readily loosened and the upperv section of the pole swung downwardly to the'position illustrated" in dottedv lines in Fig. 1= so that a: workman standing onthe roof of a car may have:convenient 'access to the trolley wheeh v I I It will be observed that when the trolley pole is attached to the stand by means of the present pole socket there is no liability of the pole. becoming: detached when being elevated-on lowered bythe conductor of the CaIL' ,:[-t ofttimes happens under the present method of attaching the poles to the trolley stand'that the pole becomes loosened from the stand and is displaced therefrom while the conductor'is pulling'dow n on the pole. Ofttimes as a result, the conductor, due to the sudden releasing of the pole, loses his balance and falls backward from the car platform;

Wedesire also to direct particular attention to the fact that the trolley pole of this invention can be readily disassembled so that the upper section of the trolley pole may be readily detached to provide for the substitution of anew trolley wheel, without requiring any special tool for it is only necessary to loosen the locking handle.

What is claimed is:

V 1. In atrolley, a stand, a pole and a connection interposed between said stand and pole comprising two members, the adjacent ends of saidmembers being provided with overlying disks, theopposed faces of which being provided with teeth, one of saiddisks having a centrally located opening, a shaft projecting. laterally from the axial center of thesecond diskand-disposed through the opening in'the'firstnamed disk, :1 member threaded upon the free extremity of the shaft for holding the disks in'assembled relation, saiddisks having annular recesses formed therein around the opening and shaft respectively, a washer seated within the recesses, V and transverse shoulders formed on both'of said disks adapted-to contact.

2. In a-trolley, a'stand, a pole and a connection interposed between said stand and pole comprising two members, the adjacent ends of" said members being provided with overlying disks, the opposed faces ofwhich being provided with'teeth, one of said disks having a centrally located opening, a shaft projectinglaterally from the axial center of the second disk anddisposed through the opening in the first named disk, a member threaded upon the free extremity of the shaft for holding the disks inassembled relation, said disks having annular recesses formed therein aroundthe opening and shaft' respectively, a. washer seated within the recesses, and transverse shoulders formed-on'both of said disks adapted to contact, each of said shouldersbeing of a width approximately equal to the combined thicknesses of the two disks,
